Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of a issued label holding mechanism of a label issuing device included in a label printer or the like.

(Prior art and its problems) To explain a weighing label printer whose conventional mechanism is shown in FIGS. 6 and 7, the weighing label printer 20 has a weighing pan 21 on the front side and a label issuing device 22 above it. Then, the head H and platen roller P print the required data regarding the product weighed with the weighing pan 21 on a label, and the issuing device 22 issues the label one by one. It is intended to hold the following.

Label A is removably attached to mount B at predetermined intervals, and when label A is peeled off by changing the direction of mount B using peeling member 1, label A is transferred diagonally downward and upward in the direction of transfer. It is sucked into the slit-shaped suction hole 3 provided and held.

In the label holding structure as described above, the frame portion including the head H, platen roller P, and peeling member 1 protrudes from the holding portion of the label A, so even if the product C is lifted and brought into contact with the product C, it will not stick properly. If the product is applied with forceful contact, the product C may be damaged, and the head H and platen roller P may be subjected to impact, resulting in printing misalignment.

In addition, conventionally, as another mechanism, the
In No. 1, there is a device in which the issued label is flown by two rollers rotating at high speed and moved to a label holding surface away from the issuing opening.

However, in the above-mentioned conventional mechanism, since the label is made to fly under the suctioned air current, there is a problem that the label transfer from the label issuing opening to the holding surface becomes extremely unstable.

(Purpose of the invention) The present invention was made in view of the above-mentioned conventional circumstances, and its purpose is to convey the issued label to a position that is convenient for work, and to hold it in an orientation that is easy to work with. It is an object of the present invention to provide a label issuing device that enables reliable label conveyance operation.

(Structure) In the issued label holding mechanism of the present invention, a frame whose bottom surface is open is attached near the label issuing port of the label issuing device, a suction fan is provided in the upper part of the frame, and a tip portion of the bottom surface of the frame is provided. A label holding member is attached to the frame body, and a cylindrical body having a plurality of annular grooves spaced apart in the axial direction on the label issuing port side of the frame and allowing the issued label to be conveyed toward the label holding member is rotatably installed, The label holding member is characterized in that a guide claw protrudes that can be inserted into the annular groove of the cylindrical body.

(Function) According to the above configuration of the present invention, the label issued to the label issuing port is attracted to the cylindrical body by the intake air flow rising in the annular groove of the cylindrical body, and is directed toward the label holding member by rotation of the cylindrical body. It is conveyed to the holding member along the guide claws while being peeled off from the cylindrical body, and is held by suction.

(Example) An example of the implementation of the present invention will be described with reference to FIGS. 1 and 2. In the figures, 1 is a peeling member, which is used to wrap a mount B and issue a label A from an issue port 8. The label issuing side of the peeling member 1, that is, the issuing port 8
A cylindrical body 2 is provided near the label so as to rotate along the label issuing direction.

The cylindrical body 2 has a hollow cylindrical shape with annular grooves 3b, 3b... formed at regular intervals in the longitudinal direction on the outer periphery,
A plurality of suction holes 3 smaller than the label A are formed in the cylinder 7 of the grooves 3b, 3b.

A frame body 11 with an open bottom is provided so as to surround the cylindrical body 2, a label holding plate 6 is attached to the bottom end side of the frame body 11, and a suction hole 4 is bored in the label holding plate 6. Cylindrical body 2 of label holding plate 6
A guide claw 5 that fits into the annular groove 3b of the cylindrical body 2 is provided on the side so that the label A can be smoothly transferred from the cylindrical body 2 to the label holding plate 6. The guide claw 5 is inserted into the cylinders 7, leaving a gap between them.

In the figure, reference numeral 10 is a suction fan provided within the frame 11, which sucks air from the suction holes 3 and 4. Further, the sensor 9 detects whether the label A is held on the label holding plate 6 or not.

Thus, the cylindrical body 2 has a lower peripheral surface that uses the annular groove 3b and the suction hole 3 as a passage for the suction fan 10.
When the cylindrical body 2 is continuously rotated, the label A issued by the transfer of the mount B is attracted to the cylindrical body 2 and reaches the label holding plate 6 while being held there. , is held by the label holding plate 6. A sensor 9 detects the presence or absence of a label, and if label A is not present, a label is issued.

In the above embodiment, the label holding plate 6 is horizontal, but it may be sloped.
In the above embodiment, in addition to the annular groove 3b, the suction hole 3 is also formed as one of the suction passages, so that the suction effect becomes more reliable.

In the embodiment described below, the same components as in the first embodiment are designated by the same reference numerals and the explanation thereof will be omitted. Note that the rotation of the cylindrical body may be continuous or intermittent, and may be arbitrary.

The second embodiment will be described with reference to FIGS. 3 and 4. This embodiment has a structure that does not include the above-mentioned suction hole 3, that is, only the annular groove 3b is used as the intake path. Further, a positioning stopper S is provided on the label holding plate 6 to position the label A.

Note that the other configurations and operations are the same as those of the first embodiment.

To explain the third embodiment with reference to FIG. 5, this embodiment is an automatic pasting type of the third embodiment, in which a label sprayer 12 is provided in place of the label holding plate 6 and surrounded by a frame 11. It is something. The label A is held by the cylindrical body 2b, reaches the label sprayer 12, and is sprayed with air.

(Effects) According to the present invention, the issued label can be guided to a location where workability is not hindered, and the label can be held in an orientation that facilitates label pasting work. That is, there is no problem with the conventional example shown in FIG. 6, where the label holding part is recessed in a stepped manner with respect to the frame of the peeling member, making it impossible to reliably attach the label. Therefore, the label can be affixed easily without damaging the product, and the printing parts such as the head and platen roller are not subjected to impact, thereby preventing printing misalignment.

In addition, since the issued label is attracted to the outer periphery of the cylindrical body and transported, the label can be transferred stably and reliably from the issuing port to the holding member compared to the flight method, and the annular groove formed on the cylindrical body , since it serves both as an air intake path and a guide claw insertion part, the suction fan is installed inside the frame, and the intake structure is extremely simplified, and the guide claw allows the label to be peeled off from the cylindrical body and held. It can be reliably transferred to the member.
